Ambush Valley

Ambush Valley is a 1936 American Western film directed by Bernard B. Ray and produced by Reliable Pictures. Under the 1909 Copyright Act, works published between 1928 and 1963 required a renewal filing with the US Copyright Office during the 28th year of their first copyright term to maintain protection. If no renewal was filed, the work entered the public domain after 28 years. A search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) reveals no record of a renewal filing for Ambush Valley. While the film was originally registered (LP6698, published November 1, 1936), the lack of a renewal in 1963 or 1964 caused the copyright to expire. This is consistent with the film's widespread presence in public domain DVD collections (such as those from Alpha Video) and availability on the Internet Archive without takedown claims from any rights holder.
